APATITE STRUCTURES, J.C. Elliott, R.M. Wilson, S.E.P. Dowker, pp. 172-181

The structure of apatite, Ca10(PO4)6F2, can be described in terms of an approximate hexagonal close packed set of spheres in which each sphere represents a tetrahedral PO4 3ion. This packing has octahedral interstitial sites that form channels through the structure parallel to the hexagonal axis. The F and 4/10ths of the Ca ions are located in these channels forming columns of F and Ca ions res...

and pp collisions 1 17 . FRAGMENTATION FUNCTIONS IN e + e − , ep AND pp COLLISIONS

The term ‘fragmentation functions’ is widely used for two related if conceptually different sets of functions describing final-state single particle energy distributions in hard scattering processes (see Refs. [1,2] for introductory reviews, and Refs. [3,4] for summaries of recent experimental and theoretical research in this field). The first are cross-section observables such as the functions...
